Dear FanFiction Writers,
The Auror department is one of integrity and excellent repute and would never lessen itself to the levels of its adversaries and sanction the use of unforgivables. They are unforgivable for a reason and are only permitted to be used if the country is at war or in situations of dire need. They are strictly forbidden to be used on a whim, so please stop questioning our reputation.
Sincerely, The Auror Department.
